This photo shows one of the drilling scars where dynamite was used to blast the stone. It also shows the incredible mess of chemicals, materials and forces that makes up the rock.
Peregrine falcons populate the rock. Famously this National Preserve was put together to try to save the species because DDT was wiping them out. And in these days of bad news the falcon story is a good one where the nestlings were bred by Cornell scientists for several decades and carefully transplant in nests in California including one here. And the species was removed from the endangered list in 2000.
